For example:
For the given tree:
The path 1 -> 3 -> 7 produces the maximum i.e, 11.
Problem approach
1) Find maximum sum from leaf to root in left subtree of X (we can use this post for this and next steps)
2) Find maximum sum from leaf to root in right subtree of X.
3) Add the above two calculated values and X->data and compare the sum with the maximum value obtained so far and update the maximum value.

0/80
Asked in companies
You are given two non-negative numbers 'num1' and 'num2' represented in the form of linked lists.
The digits in the linked lists are stored in reverse order, i.e. starting from least significant digit (LSD) to the most significant digit (MSD), and each of their nodes contains a single digit.
Calculate the sum of the two numbers and return the head of the sum list.
Example :
Input:
'num1' : 1 -> 2 -> 3 -> NULL
'num2' : 4 -> 5 -> 6 -> NULL
Output: 5 -> 7 -> 9 -> NULL
Explanation: 'num1' represents the number 321 and 'num2' represents 654. Their sum is 975.
Problem approach
Traverse the two linked lists in order to add preceding zeros in case a list is having lesser digits than the other one.
Start from the head node of both lists and call a recursive function for the next nodes.
Continue it till the end of the lists.
Creates a node for current digits sum and returns the carry.
2. Puzzle Question
There are 5 lanes on a race track. One needs to find out the 3 fastest horses among total of 25. Find out the minimum number of races to be conducted in order to determine the fastest three.
Problem approach
Tip 1 : The approach entails conducting 5 races where each race group would involve 5 horses.
Tip 2 : In the ensuing step, a sixth race is conducted between winners of first 5 races to determine the 3 fastest horses (marked A1, B1, A=and C1). The seventh race is conducted between horses B1, C1, second and third horse from the horse A1’s group (A2, A3), second horse from horse B1’s group (B2).
Tip 3 : The horses that finish 1st and 2nd in the seventh race, are actually the 2nd and the 3rd fastest horses among all horses.
